It's very difficult to ascertain, there's no one answer here, especially because the massive difference that place makes, not to even mention the rich and varied factor of time, as bows can be very different in terms of efficiency, purpose/ use, draw weight and such things also affect arrows.
Overall, as a traditional fletcher, toxophilite and bowyer, for what that's worth, I wager to say that Bannerlord has rather decently balanced archers.
An army compromised solely of archers will not win, like it did in Warband with Vaegir Marksmen armies. Mostly because they get swept aside easier it seems by cav or good shielded inf, faster than they did b4 in WB. Try an all Imperial, Sturgian, Khuzait, Batannian or Aserai archer army. You'll get bent the first time u encounter anyone with sizeable cavalry force and they swoop your men off of the field.
Maybe ranged *seems* to be doing much dmg, but this is a problem of armor in this game being not very effective at countering damage, rather than merely (ranged) weapons themselves but doing to much dmg.
